［GDC 2024］CPUを使わずにGPUが自発的に描画するパイプライン「Work Graph」がDirectX 12に正式採用 ライター：西川善司 セッションタイトルを訳すなら，「ようこそ，未来のGPUプログラミングモデル『GPU Work Graph』へ」 米国時間2024年3月18日に行われたGDC 2024の技術セッション「Advanced Graphics Summit: GPU Work Graphs: Welcome to the Future of GPU Programming」において，AMDとMicrosoftは共同で，DirectX 12の新機能「Work Graph」を発表した（関連リンク）。本稿では，Work Graphとは何で，どのような利点をもたらすのかを解説したい。 セッションを担当したMicrosoftのShawn Hargreaves氏（Dev Man
This list is illustrative of a GPU and vendor driver supporting all possible entrypoints/profiles using mesa 22.3. The actual capabilities reported in vaQueryConfigProfiles, vaQueryConfigEntrypoints , vaQueryConfigAttributes, VaQueryVideoProcPipelineCaps and others are dynamically queried from the underlying GPU and might vary between platforms and driver versions. The vainfo utility will list the
MicrosoftはWindows 10/11に、「GPUスケジューリング」機能を追加している。公式ブログによれば、WDDM（Windows Display Driver Model）2.7以降のドライバーを使用する環境で、メモリーの制御をGPUに委ねて遅延を低減し、性能を改善する機能である。 NVIDIA/AMDなどのeGPU（外付けGPU）を備えるPC環境と、対応デバイスドライバーがあれば利用可能。本機能はWindows 10 バージョン2004から搭載しているが、その頃はコロナ禍で気が滅入ってしまい、探究心が枯渇していた。最近は気持ちも安定し、逃避ではなく日々の楽しみとしてPCゲームをプレイしている。 そしてPCゲームのパフォーマンス調整を行っていた際、「GPUスケジューリング」の情報に出くわした次第だ。まずは確認方法から紹介する。 「Win」+「S」キー、もしくは「Win」+「Q」
Abstract You may have noticed a mysterious new optional feature called Hardware Accelerated GPU Scheduling appear in the advanced graphics settings page with the Windows 10 May 2020 update. The purpose of this blog is to give some background on this new feature and how we are introducing it. It is intended for folks curious about Windows internals. Remaining on the cutting edge of hardware innovat

AWS for Games Blog Splitting the Atom: Introducing Lumberyard’s New Photorealistic Renderer Authored by Chanelle Mosquera and Doug Erickson of the Amazon Lumberyard team. For over 5 years, Amazon Lumberyard‘s graphics engine has served our customers in fine stead. As we looked to our future, we recognized that its fixed approach to rendering and its established feature set would limit our customer
Bigger. Bolder. Brighter. High dynamic range (HDR) offers the most impressive improvement to the visual experience in recent history. HDR unlocks an entirely new range of colors with more intensity than standard monitors, making games come to life like never before. In November 2020, the Xbox Series X|S consoles launched with the Auto HDR feature which automatically upgrades your backwards compati
October 26, 2020 by Laszlo Agocs | Comments Last year we had a three part blog series about Qt's new approach to working with 3D graphics APIs and shading languages: part 1, part 2, part 3. For Qt Quick, an early, opt-in preview of the new rendering architecture was shipped in Qt 5.14, with some improvements in Qt 5.15. With the release of Qt 6.0 upcoming, let's see what has happened since Qt 5.15
Earlier this year, Microsoft showed the world how the Xbox Series X, with its portfolio of technology innovations, will introduce a new era of no-compromise gameplay. Alongside the actual console announcements, we unveiled the Xbox Velocity Architecture, a key part of how the Xbox Series X will deliver next generation gaming experiences. We’re excited to bring DirectStorage, an API in the DirectX

Graphics programmer spending most of my waking hours making pixels prettier and faster. This blog is my scratchpad for graphics techniques I try and experiment with. The opinions expressed herein are my own. Follow @KostasAAA I posted a few days ago a screenshot of the long shader ISA code produced by the RGA compiler for a single atan2() instruction. The post got quite a large engagement and it f
